[9] CHECK POINTS OF EVERY 1 YEAR
Replacing Air Cleaner Element
1. Remove the air cleaner element (2) once a year.
IMPORTANT
■
• The air cleaner uses a dry element, never apply oil.
• Do not run the engine with filter element removed.
• Be sure to refit the air cleaner cover (1) as shown in the
figure. If the air cleaner cover (1) is improperly fitted,
evacuator valve (3) will not function and dust will adhere to
the element.
• If it is loose, dust and dirt may be sucked in, wearing down
the cylinder and piston rings earlier and thereby resulting in
poor power output.

Flushing Cooling System and Changing Coolant
CAUTION
• Never open radiator cap when engine is hot.
• When opening, loosen cap slightly to the stop to relieve any
excess pressure before removing radiator cap completely.
1. Stop the engine and let cool down.
2. To drain the coolant, open the radiator drain plug (3) and engine
drain plug (4) and remove the radiator cap (1). The radiator cap
(1) must be removed to completely drain the coolant.
3. After all coolant is drained, fill with clean water and cooling
system cleaner.
4. Follow directions of the cleaner instruction.
5. After flushing, fill with clean water and anti-freeze until the coolant
level is just below the port.
6. Fill with clean water and anti-freeze upper level of the recovery
tank (2).
7. Start and operate the engine for few minutes.
8. Stop the engine. Check coolant level and add coolant if
necessary.
9. Install the radiator cap (1) securely.
IMPORTANT
■
• Do not start engine without coolant.
• Use clean, fresh water and anti-freeze to fill the radiator and
recovery tank.
Refer to “LUBRICANTS, FUEL AND COOLANT”.
(See page G-8)
• When the anti-freeze is mixed with water, the anti-freeze
mixing ratio must be less than 50 %.
• Securely tighten the radiator cap (1). If the cap is loose or
improperly fitted, water may lead out and the engine could
overheat.
